Well I managed not to flood the house, and after a bit of swearing and acting like a contortionist the tap's all plumbed in.

I used a pair of compression fit joins, and I'm loathed to tighten them any more but it was leaking ever so slightly.

I also noticed that for some reason the toilet ball-cock thingy wasn't turning off properly and was still letting water in even when it was full. It happened after I turned the water back on, so I've wound the main stop cock back in a couple of turns which seems to have fixed the loo and the leak from the tap area appears to have stopped too.

The house does have very good water pressure, so I presume I'm doing no harm by closing the tap a little?

Seeing as the kitchen's going to be ripped out and moved, I'm not overly concerned!
